1/4x2(4x+8y)-3/5x(25x2-20xy)​

On the photo it shows all the steps you need. Next time you should make the multiplying symbol to this * instead it'll be easier to understand because if it was a or a multiply symbol

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
